Sean Clode continues to influence his victim, who five months ago skipped school and travelled hundreds of miles from the north of Scotland to meet the man who befriended her over the internet, Teesside Crown Court heard.
Judge Howard Crowson told unemployed Clode, of Hartlepool, the age of consent laws were needed to protect vulnerable teenagers from men like the defendant.
The pair had met at the railway station in Hartlepool and camped overnight on nearby dunes in a tent she had bought on her way there. They had sex on at least two occasions during the night, despite him knowing she was underage.
She had pretended to her parents she was going to school then going on a sleep-over with a friend, but instead met up with Clode.
When it became apparent she had vanished, her frantic father drove through the night, first to Edinburgh, then on to the north-east, desperately searching for the teenager.
He asked postmen, knocked on doors and wandered the streets looking for her, having arrived at dawn.
He finally heard she was safe at 2.30pm, by which time he had begun to wonder if he would see her alive again.
Footage from a police helicopter showed Clode getting out of the tent and putting on his trainers, while the girl, who cannot be named, pulled her dress down.
The next day the girl told police in a recorded interview that she had sex several times that night with Clode in the tent.
But the following month she changed her story and said no sex had taken place, in a bid to protect the man with whom she was still infatuated.
The judge concluded she was acting on his wishes by giving a false account.
The jury deliberated for just in excess of an hour before convicting him of sexual grooming, child abduction and two counts of sexual activity with a child.
The abduction charge related to Clode removing the girl from the lawful authority of her parents.
He denied all offences, denying sex had taken place and claiming the girl arrived in Hartlepool without his knowledge and that he was merely trying to keep her safe.
The case has continued to drive a wedge between the girl, who cannot be identified, and her family.
Rebecca Brown, defending, said her client did not set out to groom the girl when they chanced upon each other while playing Xbox games online.
Sentencing him to six years, Judge Crowson said: "Your intention was clearly to coerce her into sexual activity. This case demonstrates why the age of consent law is necessary to protect 14-year-old girls.
"You are a selfish man interested only in your own sexual desires."
Clode was made subject to a Sexual Offences Prevention Order, will sign the sex offenders register and may be barred from working with children.
